Hmmm.. I have never given it any thought but I didn't realize there were legal issues. So, let's say I had a Ruger Blackhawk with a 7.5" or 10.5" barrel. If I were to somehow fashion a device which clamped onto the regular hand grips that allowed me to have the device pressed up against my shoulder, I might have violated a law? I think I remember seeing some similar device in an old Clint Eastwood western.
